- IMPROVED SASH-FASTENING.

TO ALL WHOM I'l MAY CONCERN:

Be it known that I, JOSIAH WARD CHILDS, of Cincinnati', Hamilton county, and State of Ohio, have invented a new and useful Improvement in Sash-Fasteners, of which the following is a full and clear description, reference being had to the accompanying drawings, forming a. part of this specification.

Figure 1 is a perspective view of a window-frame and sash with my improved fastener attached.

Figure 2 represents one form of my improved fastener, constructed with a view to great security.

Figure 3 represents a simple form of fastener, and its operation in securing the sash in any desirable position.

My invention rela-tes to a window-fastener so constructed that it will prevent rattling or shaking ofthe sash in the frame of the window; also fastening the sash either up or down.

A is the window-frame, in which moves the sash B. The construction of the most simple fastener is represented in g. 3. It is composed ofthe sliding-plate a and guides b. The sliding-plate a is of metal, of suitable form, is perforated with the diagonal slots c. Guides I pass through slots c, and at the same time hold plate a in contact with frame A. IThe edge of sliding-plate a, next to sash B, is turned up, forming lip a', which comes in immediate contact with the sash. A handle, a, projects from lipl a. Pin d is secured in the sash in line with lip a. When the sash is do\vn,'the pin d engages the lower end of lip a of sliding-plate a. In attempting to raise the window without throwing diagonally backwards the sliding-plate (z, lip a acts upon the sash as one face of a wedge. The same is the case when the sash is raised, and pin d rests upon lip a', (shown in red in fig. 1 and fig. The weight ofthe window presses the wedge-shaped parts of sliding-plate a between guides b and the sash, thus eifcctually securing the window open, and at the same time preventing rattling. Forrailroad cars or vehicles of any description the simple form of fastener, as above described, is very desirable.

A more secure fastener, embodying my improvement, is shown in detail in iig. 2. Ilate c, having the diagonal slot f, is secured to the inside of window-frame A. A rib, g, projects from the back of plate c, runs parallel to slotf. Wedge L moves freely upon rib g, guided by handle'lc, which passes through slot f pivoted to plate e. Immediately over handle k is latch Z. When it is desired to secure the sash down, the wedge h is moved down rib g till its lower end or point 4L bears upon step m in sash, as shown in Figure 4. The latch lis thrown downengaging the handle It, eiectnally locking the sash down. When the window is open, the lower rail of the sash may rest upon the top or butt end of wedge z; or, when it is desirable to have the window partly open, the Wedge i, being between the sash and rib g, holds the sash in position. Onc or more fasteners may be used upon each sash, two being necessary where much jar is encountered.

Having fully described my improved sashfastener, and the mode of'operating it, I make the following claims:

1. The slotted sliding-plate a, thumb-pieee a, slots c c, and guide-pins Z2 I), constructed and arranged as above described and for the purpose set forth.

2. The plate e, latchAZ, in combination with sliding-wedged, as above described and for the purpose set forth.

JOSIAII WARD CHILDS.
